# Optionally convert to .x65 x65wrap -i backup.bin -o backup.x65 | Method | Typical Tools | Steps | |--------|---------------|-------| | Standalone ISP programmer | XFlashProg , FlashCatUSB , Segger J-Link (with flash driver) | 1. Connect programmer to the SPI pins (CS, SCK, MOSI, MISO). 2. Load .bin / .x65 in the GUI or CLI. 3. Verify/Erase/Program. | | Bootloader‑based update | XBootloader (UART, USB, CAN), custom bootloader firmware | 1. Put device in bootloader mode (e.g., pull BOOT0 low, send “0x55” over UART). 2. Transfer the flash file using XModem/YMODEM or a custom protocol. 3. Bootloader validates CRC and flashes. | | In‑system (via MCU) | HAL HAL_FLASH_Program() , X6512_Prog() API | 1. Load the binary into RAM (e.g., via UART). 2. Call the flash‑write routine sector‑by‑sector. 3. Optionally verify with HAL_FLASH_Program() return status. | Example: Flashing via XFlashProg (CLI) # Erase the entire chip first xflashprog -p /dev/ttyUSB0 erase

Use the partial‑program feature of the bootloader: send a small *.bin that contains the new config and the address offset. The bootloader will erase only the sector containing the config and rewrite it.
